BullseyeBore Core CG1-101 Drill Guide with Green Laser - Magnetic Alignment for 2 to 8 Inch Bits

Precision you can rely on

In busy workspaces, accuracy matters. The BullseyeBore Core CG1-101 uses a high-visibility 520 nm green laser to project three patterns that clearly indicate when the drill is perpendicular to the surface. When the concentric circles align, you’ll see a straight hole form with minimal trial and error, reducing guesswork and rework.

Key capabilities

This magnetic guide is designed to work with your existing drill setup. It attaches quickly to drill chucks in seconds and lets you switch between guided and unguided drilling without tools.

• Three bright green laser patterns for flexible alignment
• Supports bits from 2" to 8", including Spade, Auger, Forstner, Step, and Aircraft types
• Magnetic attachment enables fast, tool-free setup
• Low-profile sight lines keep the bit and work surface in view

Universal compatibility and setup

Designed for diverse workshops, the Core CG1-101 works with thousands of common drill chucks and a wide bit range. It’s ready to go with your existing equipment and you can switch modes instantly when the job changes.

Safe, non-contact operation

The magnetic connection is designed to break away instantly if contacted, protecting both the tool and the workpiece. The system never touches the workpiece, helping prevent scratches or marks while you drill.

Performance in your space

Optimized for indoor workshops and indirect sunlight, the Core CG1-101 shines in typical shop lighting and shaded outdoor areas. It does not operate in direct sunlight, so plan for covered or indoor use when precision matters most.
